Since I'm taking out the diff to put in the new cusco unit I'm not totally sure what other parts are needed....could someone post a list of what OEM parts will be needed?



I'm guessing it's a good idea to replace some of the stock bearings and whatnot inside the diff. I just need a list...



Thanks,

You are going to need shims to get the back lash and stuff correct. or it will totally ******* suck.

Well yes the "proper industry" way to do it would be new shims and to measure run out and crap, remove the pinion gear, replace the bearing and crush washer too, but honestly you really don't have to. I speak from experience on this one.

You need new bearings for the diff, and you have to have them pressed on. If you are using the same ring gear then everything will line up correctly when you re-assemble.

So if you are doing it yourself I would do it what way. I've seen it done, and have done it on cars with over 400hp at the wheels with no problems. You just have to make sure what side what shims came out and put them back the same way. Otherwise you will chew the **** outta the gears.

I took out the pinion once, and reused the crush washer. The gear ware rate was fine, but the backlash was fucked up. I put it together and it wined like a **********er. I have the new crush collar but i havent had time to take it apart again.

Thanks for the info....I will not be actually putting the diff in...I don't want to mess with that crap, but I will be taking the pumkin out. I just want to have all the parts necessary for the install. I don't feel like messing with the internals of the diff at all. I do pretty much everything else, but I don't want to set it wrong and screw things up. While it's out I'm gonna get the pumkin powdercoated as well, don't like things all rusty.

i installed the kaaz in my 240......just take like turbovr6 said. pull it out and reinstall exactly the same way. my friends and i have even spoken to kaaz usa and they say yeah no need to do backlash adjusting unless you think you have a problem with the ring and pinion

i am with vosko and vr6 on this one. you have no idea how bad guys will flat rate a diff install and it be fine. no torque wrench or any measurements. that said everyone should do one "the right way" once

rfreeman27

That is if you do NOT take the pinion out.



If you do, then you need to set the backlash.

pre load is more important. seen it set with a air gun more times then i can count. lol. after you have done a bunch of rear ends you do get a feel for what will and will not fly.

pre load is so easy to set properly, why would you not do it?



tighten, check with oirque wrench, then adjust as needed
